Genome-wide detection of copy-number variations in local cattle breeds
2019
The aim of the present study was to identify copy-number variations (CNVs) in Cinisara (CIN) and Modicana (MOD) cattle breeds on the basis of signal intensity (logR ratio) and B allele frequency of each marker, using Illumina’s BovineSNP50K Genotyping BeadChip. The CNVs were detected with the PennCNV and SVS 8.7.0 software and were aggregated into CNV regions (CNVRs). PennCNV identified 487 CNVs in CIN that aggregated into 86 CNVRs, and 424 CNVs in MOD that aggregated into 81 CNVRs. SVS identified a total of 207 CNVs in CIN that aggregated into 39 CNVRs, and 181 CNVs in MOD that aggregated into 41 CNVRs. The CNVRs identified with the two softwares contained 29 common CNVRs in CIN and 17 co…
Pellets based on polyuronates: Relationship between gelation and release properties
2017
International audience; Three polyuronates: amidated low methoxyl pectin (ALMP), low methoxyl pectin (LMP) and polygalacturonic acid (PGA) were used to encapsulate rutin in pellets, and they were characterized by different techniques (macroscopic properties, Calcium and rutin release). The ability of the three polyuronates to bind calcium ions and the viscoelastic properties of gels were performed to relate the properties of the pellets to the gel structures. The pellets size, the water content, the water uptake, the release of calcium and rutin varied depending on the polyuronate used. The pellets size of ALMP were smaller than LMP and PGA with a lower water content, but this matrix was mo…
Transarteriālas ķīmijterapijas pielietošana aknu audzēju ārstēšanā
2016
Ievads: Transarteriāla ķīmijembolizācija ar medikamentus izdalošām mikrosfērām (DEB-TACE) ir audzēja apasiņojošo artēriju oklūzija digitālās subtrakcijas angiogrāfijas laikā, izmantojot mikrosfēras piesūcinātas ar ķīmijembolizācijas materiālu, kas pēc ievades pagarina saskares laiku starp audzēja šūnām un ķīmijterapijas medikamentiem. DEB-TACE tiek plaši pielietota hepatocelulārās karcinomas (HCC) paliatīvajā ārstēšanā, kad rezekcija vai ablācija nav iespējama. DEB-TACE tiek izmantota arī citu hipervaskulāru nerezicējamu aknu audzēju, piemēram, holangiokarcinomas, kolorektālu aknu metastāžu ārstēšanā. Optimāli kandidāti ārstēšanai ir Child-Pugh A un B klases pacienti ar lielu vai multifokāl…
Optimizing the Shape of Welded Constructions Made through the Technique “Temper Bead Welding”
2020
Welded constructions are subject to high stresses during operation. One solution for improving the behavior in exploitation of welded constructions in various cases is to use the welding technique “temper bead welding” (TBW). In the paper, the optimization of the geometry of the welded joints by the TBW technique was performed. Thus, corner welded joints made of S355 steel were analyzed. To make the welded joints, three layers of welding seams were deposited, and the intermediate layers were processed through cutting with various radii. To analyze the influence of the size of these rays on the behavior of welded constructions, a research program based on factorial experiences wa…
EFFECT OF IONIC STRENGTH AND MEDIUM COMPOSITION ON THE REMOVAL OF Pb2+ BY ALGINATE GEL BEADS. DPVASV AND ICP-OES MEASUREMENTS.
2012
The biosorption, i.e. a passive sequestering process by metabolically inactive biomass, shows a growing interest for toxic metal ions removal from contaminated aqueous solutions (1), such as municipal and industrial wastewaters. Since the sorption mechanism occurs mainly by ion exchange between the metal ion present in solution and the counter ion of the biopolymer (2), the efficiency of the sorption process largely depends on ionic strength and on the medium composition of solution containing the metal ion to be removed. In order to evaluate quantitatively the influence of ionic strength and medium on the metal removal process by the biomass, we report here results of a study on the sorpti…
